How to switch between old Outlook and new Outlook

The new Outlook application is significantly improved with a fresher interface, along with some different options compared to the old Outlook. However, not everyone is familiar with the new Outlook interface and wants to return to the old Outlook to use the full features and more customizations on Outlook. Below are instructions for switching between the old Outlook and the new Outlook.

Instructions for switching between old Outlook and new Outlook

If you are using the old Outlook, to switch to the new Outlook, users just need to activate the New Outlook switch button in the top right corner of the interface.

Immediately after that, the Outlook interface switched to a new version for users to experience.

In case this New Outlook button is not available, click Help then to return to the old Outlook interface, click Go to Classic Outlook and you're done.

Or we can switch to off mode at Try the New Outlook to turn off using the new version of Outlook.
